Definitions

  • the present invention relates to a handle with inseparable attachment, for a cooking container.
  • Common containers for cooking food for example pans, pots and casseroles, are provided with grips, i.e. handles, adapted to facilitate gripping of the container without the risk of burns.
  • the pans have a single elongated grip, called handle, fixed to a cooking container which houses the food and which is placed on a heat source, for example a gas stove.
  • a heat source for example a gas stove.
  • the handle is made of thermosetting material, for example bakelite, thermoplastic material or silicone.
  • the handle is usually fixed to the cooking container by a metal attachment comprising a plate for direct fixing to the cooking container by welding or rivets.
  • connection between the metal attachment and the handle is normally irreversible and is made in the factory by overmolding, gluing or with screws or rivets.
  • GB-2347641 describes a method of irreversibly connecting a metal attachment to a handle, comprising the use of a mold.
  • the metal attachment includes a gripping area protruding in a direction orthogonal to the longitudinal direction of the handle, in which said gripping area is coupled with an undercut of a seat of the handle.
  • GB-2183196 describes a system for fixing a handle to a cooking container comprising an intermediate cup-shaped element having a base and four side walls extending from the base and which are separated from each other by slits. Two opposite side walls include teeth protruding outwards.
  • EP-3260027 describes a metal attachment for a handle comprising elastically deformable fixing means adapted to incline below a lower surface of the metal attachment.
  • said fixing means are complex to make, as the shape of the seat inside the handle which must have walls adapted to oppose the uncoupling of the handle from the metal attachment.
  • Object of the present invention is to provide a gripping assembly for a cooking container of food, comprising a handle and a metal attachment adapted to fix the handle to the cooking container, wherein the coupling between the handle and the metal attachment is irreversible.
  • a further object of the present invention is that said irreversible coupling is simple to make and stable.
  • Still a further object of the present invention is that the metal attachment is economical and adapts to normally used handles, comfortable for the user.
  • a gripping assembly for a cooking container of food comprising a handle and a metal attachment able to fix the handle to the cooking container, wherein the metal attachment is irreversibly coupled to the handle and comprises a plate for fixing to the cooking container,
  • the asymmetry of the teeth with respect to the central axis determines a secure grip of the quick coupling to the seat.
  • the handle In order to achieve said deformation, the handle must be made of bakelite or other material which allows said deformation, for example wood or soft plastics such as nylon or moplen.
  • the gripping force acts in the direction of the lines orthogonal to the central axis, in particular outwards, or in the direction in which the teeth protrude.
  • the toothed elements remain parallel to the direction of the central axis, namely there is no transverse stress.
  • a gripping assembly 1 for a cooking container of food comprises a handle 2 and a metal attachment 3 adapted to fix the handle 2 to the cooking container (not shown in the figures).
  • the handle 2 is for example a handle of a pan, namely it has an elongated shape with a prevalent longitudinal direction, as shown in the figures.
  • the metal attachment 3 comprises a plate 4 for fixing to the cooking container, for example by welding or rivets, and a quick coupling 5.
  • the handle 2 comprises a seat 6 and is preferably made of bakelite.
  • the quick coupling 5 is adapted to couple to the seat 6 so as to make the handle 2 irreversibly integral with the metal attachment 3.
  • the quick coupling 5 comprises two toothed elements 7 having an elongated shape in the direction of a central axis 10 which separates a space between the two toothed elements 7 which are parallel to each other.
  • Each toothed element 7 comprises a plurality of teeth 8 protruding outwards, wherein the teeth 8 of a toothed element 7 are misaligned with respect to the teeth 8 of the other toothed element 7, with a misalignment D along the central axis 10 with respect to lines 9 orthogonal to the central axis 10, namely the toothed elements 7 are asymmetrical with respect to the central axis 10 ( figures 7 and 8 ).
  • Each toothed element 7 further comprises an inclined outer edge 20, said inclination occurring towards the central axis 10 proceeding towards the free end of the toothed element 7, before the teeth 8.
  • each toothed element 7 includes straight inner edges 11 joined together by an inner groove 12.
  • the quick coupling 5 has a substantially U-shape, with teeth 8 protruding outwards from the legs of the U.
  • the seat 6 of the handle 2 comprises two housings 13 for respective toothed elements 7, separated by a body 14 ( figure 5 ).
  • Each housing 13 has a straight inner edge 15 and an inclined outer edge 16, said inclination occurring outwards with respect to the central axis 10, proceeding towards the open end of the housings 13 through which the quick coupling 5 is inserted.
  • the housings 13 also have a closed end 17 with an undercut 18.
  • the coupling of the metal attachment 3 with the handle 2 is very simple: it is sufficient to insert the toothed elements 7 in the respective housings 13 until the last teeth 8 of each toothed element 7 couple with the undercut 18 of the respective housing 13.
  • the housings 13 are sized so as to allow the insertion of the toothed elements 7, wherein the teeth 8 interfere with the inclined outer edges 16 of the housings 13.
  • the conical seat of the handle 2 facilitates the insertion of the toothed elements 7 the inclined outer edges 20 of which couple with the inclined outer edges 16 of the housings 13.
  • the teeth 8 are sized so as to put pressure on the outer edges of the seat 6 which deforms as a result of said pressure.
  • Each outer edge of the seat 6 at least partially comprises the inclined outer edge 16.
  • the asymmetry of the teeth 8 with respect to the central axis 10 determines a secure grip of the quick coupling 5 to the seat 6.
  • the handle 2 In order to achieve said deformation of the seat 6, the handle 2 must be made of bakelite or other material which allows said deformation, for example wood or soft plastics such as nylon or moplen.
  • the misalignment D of the teeth 8 is preferably less than one millimeter, preferably between 0.2 mm and 0.5 mm, even more preferably equal to 0.3 mm.
  • the gripping force acts in the direction of the lines 9, in particular outwards, namely in the direction in which the teeth 8 protrude.
  • the toothed elements 7 remain parallel to the direction of the central axis 10, namely there is no transverse stress, namely orthogonal to the plane identified in figures 4 and 5 .
  • the gripping assembly 1 according to the present invention is particularly resistant to traction as demonstrated by a test carried out in a quality control laboratory called "Sigma Tre Lab” in Garbagnate Monastero (Lecco, Italy).
